CANARM - Replacement Element for Heated Waterer

The heating element is the most likely component to fail over time in a Canarm heated waterer. Here are the key signs it needs replacement:

• Water is freezing in temperatures where it previously did not — the most obvious sign the element has failed.
• The indicator light stays off even in cold weather when the thermostat should be calling for heat. If the light is off and the water is cold, suspect the element first.
• Tripped GFCI breaker — a failed element can cause ground faults. If your GFCI keeps tripping, disconnect the waterer and test the element resistance with a multimeter. A functional 300W (H50) element reads approximately 48 ohms; a 500W (H100) element reads approximately 29 ohms.
• Burn smell or visible scorching on the element body.

Before replacing the element, also check the thermostat — a failed thermostat that never calls for heat can mimic element failure. Swapping the element first is usually the correct diagnostic step since elements are the higher-failure component.

Replacing the Canarm heating element is a straightforward repair accessible through the hinged access cover on the underside or side of the waterer:

1. Disconnect power — unplug the unit or turn off the circuit breaker. Never work on the unit while energized.
2. Drain the waterer — open the drain plug and allow the bowl to empty completely.
3. Open the access cover — the hinged cover on the waterer body gives access to the internal components without disassembling the entire unit.
4. Disconnect the element leads — photograph the wiring before disconnecting so you can match connections on reassembly.
5. Remove the element — it is typically secured with a mounting flange and bolts. A deep socket set is useful here.
6. Install the new element — torque the flange bolts evenly to ensure a watertight seal. Reconnect the wiring per your photo.
7. Close the cover, refill, and test — monitor the indicator light to confirm the thermostat is calling for heat and the element is responding.

If you are not comfortable with electrical work, a local farm equipment dealer or electrician can complete this repair quickly.

This listing covers Canarm's replacement heating elements for both the H50 and H100 steel waterers — however, they are different parts with different wattages:

• H50 element: 300 watts — for the 50-head steel waterer
• H100 element: 500 watts — for the 100-head steel waterer

Please confirm your model before ordering. The model number is printed on the data plate affixed to the waterer body. Installing the wrong wattage element will either result in insufficient heating (too low) or excessive heat cycling and potential overheating (too high).

If you are unsure which part you need, check the model number on the data plate affixed to the waterer body before ordering.
